抗应变干扰温度传感纤维的制备及性能研究
Preparation and performance study of strain-insensitive tem-perature sensing fiber
摘要
Abstract
To address the issue that traditional temperature sensors are easily affected by strain during human move-ment or in complex industrial environments,a strain-insensitive temperature sensing fiber was fabricated through inter-nal helical structure design and regulation of the mass fraction of multi-walled carbon nanotubes(MWCNTs).Using a three-layer coaxial wet-spinning technique,thermoplastic polyurethane(TPU)/MWCNTs composite,deionized water,and TPU solution were simultaneously pumped into the inner,middle,and outer channels respectively.Under the spatial confinement of the outer TPU layer,continuous preparation of helical fibers was achieved via the release of accumulat-ed stress and the"liquid rope coiling effect".The results show that under 20%strain,the resistance change rate of long-pitch fibers is about 6%,and ranges from 10%to 30%under 50%～100%strain The ΔR/R0 of the long-pitch fibers de-creases with increasing temperature,with a curve slope of-0.40%/℃,indicating excellent temperature sensitivity.When subjected to strain,the sensing fiber can still stably monitor changes ambient temperature,providing new in-sights for the design and development of strain-insensitive temperature sensors.关键词
